I would not lead them further north
The association of the north with the realm of Satan is deeply embedded
in Christian mythology, perhaps justifying Dante's depiction of the
lowest circle of Hell, in which Satan is trapped, as ice-bound.
Certainly, in Paradise Lost Milton knowingly exploits this
association, as at the very moment in which Satan's revolt against God
materializes he retreats to the north:
Of all those myriads which we lead the chief;
Tell them, that by command, ere yet dim night
Her shadowy cloud withdraws, I am to haste,
And all who under me their banners wave,
Homeward, with flying march, where we possess
The quarters of the north; there to prepare
Fit entertainment to receive our King,
The great Messiah.
